# Queries (`vim.treesitter.queries`)
|
|
|
|
Queries allow you to change Neovim's behavior based on Tree-sitter.\
|
|
Read more about it in the
|
|
[neovim docs](https://neovim.io/doc/user/treesitter/#_treesitter-queries).
|
|
|
|
**Example:**
|
|
|
|
In the following example, we are creating a custom injection, to highlight the
|
|
Lua string after `mkLuaInline`.
|
|
|
|
```nix
|
|
foo = mkLuaInline ''
|
|
function bar()
|
|
return 'foobar'
|
|
end
|
|
'';
|
|
```
|
|
|
|
```nix
|
|
{
|
|
vim.treesitter.queries = [{
|
|
type = "injections";
|
|
filetypes = ["nix"];
|
|
content = ''
|
|
;; extends
|
|
|
|
((apply_expression
|
|
function: (variable_expression
|
|
name: (identifier) @_func
|
|
(#eq? @_func "mkLuaInline"))
|
|
|
|
argument: (indented_string_expression
|
|
(string_fragment) @injection.content)
|
|
|
|
(#set! injection.language "lua")
|
|
(#set! injection.combined)))
|
|
'';
|
|
}];
|
|
}
|
|
```
|
|
|
|
This will generate a `queries/nix/injections.scm` in a Neovim runtime directory.
|
|
|
|
> [!NOTE]
|
|
> When multiple queries match the same `filetype` and `type`, they are merged.
